So I looked at the ingredients:
Butternut tree extract - Laxative
Dandelion Root - Diuretic (causes water loss)
Boldo - Diuretic (causes water loss)
Fucus - source of iodine (claim is that it helps with thyroid function, this would only be true if you were deficient in iodine. Not really an issue in most first wold countries)

So basically, this is a pill that is designed to make you believe you are losing weight but won't cause any weight loss itself.

Thanks for that breakdown that's really helpful! I am definitely not going to buy them now after that.
